Physical centrifugal force demonstrator

Abstract

The invention relates to the technical field of teaching, in particular to a physical centrifugal force demonstrator, which comprises a controller panel, a frequency converter, an electronic digital display tension meter, a leveler and a supporting component, the controller panel is fixed to one side of the supporting component, a connecting component is fixedly arranged on one side of the supporting component, and a guide component is fixedly arranged on the side, away from the supporting component, of the connecting component. The leveler is fixed to one side of the guide component, a plurality of guide holes are formed in one side of the guide component, and adjusting components are arranged on the inner sides of the guide holes in a sliding mode. By arranging the leveler, the supporting component, the connecting component, the guide component, the adjusting component, a rotating shaft, a rotating component, a speed-adjustable motor, a second guiding component, a first sliding component, a second sliding component, a loading component, a weight component and a protection component, the physical centrifugal force demonstrator has the functions of facilitating levelness adjustment, automatically demonstrating, automatically adjusting the rotating speed, rapidly adjusting, facilitating mass adjustment, protecting and the like.

Description

technical field [0001] The invention relates to the field of teaching technology, in particular to a physical centrifugal force demonstrator. Background technique [0002] Teaching is a human-specific talent training activity composed of teachers' teaching and students' learning. Centrifugal force is a virtual force and a manifestation of inertia. It keeps the rotating object away from its center of rotation. In Newtonian mechanics , it has been used to express two different concepts: an inertial force observed in a non-inertial frame of reference, the balance of centripetal force, and under Lagrangian mechanics, centrifugal force is sometimes used to describe Generalized force under coordinates, centrifugal force is a manifestation of inertia, which does not actually exist. In order to make an object move in a circle, the object needs to be subjected to a force pointing to the center of the circle—that is, centripetal force. At present, teachers need to use centrifugal forc...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the centrifugal force demonstrator in the prior art has no automatic demonstration function, requires the teacher to perform manual rotation operation, which is inconvenient to use, and the speed of rotation needs to be controlled by the teacher intuitively, so that It will cause the experimental results to be less accurate, and the distance between the measured object and the rotation center cannot be adjusted, the quality of the measured object is not easy to adjust, and the use method is relatively simple, resulting in the disadvantage of poor demonstration effect.
